ECU question

[dante2]

I recently got my REM installed and after talking with Nick about some issues we discovered that the REM is saying I have a manual ECU. PO told me he replaced the ECU before I bought the truck and I did have to bolt it back up myself. Now the truck has been an auto since it rolled out of the factory so do I need to get an auto ECU? Nick believes it's a good idea anybody agree or disagree with that?

Does it currently work?

 

There apparently isn't much difference between them.

[dante2]

Idle is running between 900-1k+. Sprayed hoses and can't find a vacuum leak.

TPS adjusted correctly?  IAC is actually functioning?  Throttle is actually closing?

[dante2]

TPS at .85 or 17%. IAC was cleaned when I did the throttle body. Throttle appears closed.

You could try swapping it but my gut says it isn't the problem.

Auto ECU has P/N function. The purpose of this function is to add ≈50 rpms in anticipation of the new load added to the engine when shifted into gear. In reality it backs off IAC (more air) to maintain the same idle rpms. With the Auto ECU you may be able to lower your idle rpms by ≈50 rpms. As mention above, adjust your TPS again and check throttle plate using cruiser54 tip #14.

I've used them interchangeably and Ohm is correct. It's not a deal breaker to have a MT ECU in an auto vehicle. 

 

Search elsewhere for your issue.
